DEVICE FOR PRODUCING BAGS BY MEANS OF A MANDREL WHEEL |
摘要 |
A device for producing tubular wrappings for paper bags with a mandrel wheel rotating stepwise in a horizontal plane and having horizontally outwardly extending pairs of spaced parallel folding mandrels. The blanks of bag material are fed horizontally toward a position below the folding mandrels and are brought into contact pressure with a bottom face of the folding mandrels by upwardly moving folding boxes, whereupon a folding fork associated with each folding box moves upwardly to place and wrap the blanks against the sides and around the folding mandrels with the assistance of compressed air.
